In the prosperous but decadent Binhai City, under the bright lights and feasting, the evil force "Qinglong Gang" dominates the sky. Lin Yu, a mechanic, was involved in a gang dispute for no reason. His friend A Ming died trying to save him. Hatred and helplessness drove him into the underworld. In the gang, he experienced power struggles, brother betrayal, and physical and mental torture.
Until the kind and brave female reporter Su Yao appeared, she was like a beam of light shining into Lin Yu's dark world, rekindling his desire for light. Lin Yu began to secretly collect ironclad evidence of the Qinglong Gang's crimes in an attempt to put an end to it all. However, things were revealed and he was in dire straits. At the critical moment, Su Yao called the police, and the police arrived in time and destroyed the Qinglong Gang in one fell swoop. Lin Yu struggled in the darkness and finally ushered in the dawn of rebirth. What awaited him was an unknown but hopeful new life.
